A Chilean(智利) soap-opera star, a beauty from Ancient Pompeii and a freckled (雀斑的)boyish girl hardly make an average beauty show line-up.

The first world-wide digital beauty contest to the surprise of many online fans was won by a woman who is virtually(虚拟) real flesh and bones. “Virtual models are not the anti-real, they are a different representation of reality,” said Franz Cerami, the organiser of Miss Digital World (数字世界小姐).

Each of the contestants had to provide the charming photo of high degrees, with date of birth and body measurements.

Chilean Rodolfo Perez Ayala decided that no figure of his imagination could beat the beauty of his wife, Katty Kowaleczko, so he hired artist Flavio Parra to recreate her. Kowaleczko, who plays Paula Sandoval in the popular Latin American soap opera Tentacion, was transformed into Katty-ko and won the digital contest with more than 17,000 online votes.

“I’m so happy Katty-ko won. I think her strength is her similarity to a real woman-not too luxurious or exposed”, Kowaleczko, 40, told reporters. “Her beauty is in her simplicity.” Kowaleczko was not afraid of being replaced by her 3D clone in movies or theatres, but hoped she would become “a sort of ambassador(使者) of Chilean beauty”.

Cerami said Latin American interest in Miss Digital World had greatly increased since Katty-ko joined the contest, which attracted about 3600 entries from countries from Iran to Australia and even from the ancient Roman empire.

“Pompea” was the digital reconstruction of a young woman killed by the outbreak of Vesuvius in 79 AD. “She was a slave, but also a rich man’s lover. When her body was discovered, many jewels and a bangle(手镯) with the writing ‘from the master to his servant girl’ were found” said Genny Tortora, a professor at the University of Salerno who led Pompea’s creative team.

Other contestants included Kaya, the most realistic model with digital freckles, pouty (噘起的) lips and upturned nose.

Now, Cerami’s dream is to manage a form of virtual beauties, introducing them for calendars, games, ads, and movies. One is even reported to be heading for Playboy’s front page.
